Join the many thousands of software developers who are already more productive with help from the Tcl programming language and the Tk graphical user interface toolkit. Tcl Tool Command Language is a very powerful but easy to learn dynamic programming language, suitable for a very wide range of uses, including web and desktop applications, networking, administration, testing and many more.
A variable is an identifier which holds a value. In other words, a variable is a reference to a computer memory, where the value is stored. Look at some example for case sensitive variable. The unset command is used to destroy a variable. Curly braces in TCL group words together to become arguments. Characters within braces are passed to a command exactly as written. Square brackets are used to create nested command. Simply put, output of one command passed as argument to another command.
See below commands to print keys, key value pairs and values of array. Items of data passed to a script from the command line are known as arguments. The number of command line arguments to a Tcl script is passed as the global variable argc. The name of a Tcl script is passed to the script as the global variable argv0 , and the rest of the command line arguments are passed as a list in argv.
Expression is constructed from operands and operators. It's evaluated with "expr" command. Operators are evaluated based on precedence and associativity. TCL language has built-in operators as below. A TCL expression consists of a combination of operands, operators, and parentheses. Let see example of Arithmetic operators in TCL. Checks if the value of left operand is greater than the value of the right operand. If yes, then condition becomes true and return 1 else return 0.
Check if the value of left operand is less than the value of the right operand. If any of the two operands is non-zero, then condition becomes true and return 1 else return 0. Used to reverse the result of any expression. Machine intelligence is an umbrella term that's used to describe the accuracy of a machine learning ML , deep learning DL or classical algorithm output. In business-to-business B2B marketing, the term is also being used to describe a growing market segment for information technology IT View Full Term.

Tool command language Tcl is a powerful scripting language with programming features. Tcl is used for Web and desktop applications, networking, administration, testing, rapid prototyping, scripted applications and graphical user interfaces GUI. Introduced in by John Ousterhout, Tcl is used for common gateway interface CGI scripting and serves as the Eggdrop bot scripting language.
Tcl features include:. By: Justin Stoltzfus Contributor, Reviewer. By: Satish Balakrishnan.
